EXTENSION-TABLE.

Specification of Letters Patent.

Patented May 20, 1919.

Application filed May 15, 1918. Serial No. 234,761.

To all whom it may concern:

Be it known that we, GEORGE HOWARD Ross and ALFRED ANDERSON, both of the town of Fort Frances, in .the Province of Ontario, Canada, have invented certain new and useful Improvements in Extension-Tables, of which the following is the specifica tion. 7

The invention relates to improvements in extension tables, and the principalobject of the invention is to provide an extension table in which the table leaves can befstored and which is arranged and constructed so that by mechanical manipulation the leaves can be successively brought into place for use and so that by reversal of the same action they can, when desired, be put back in the stored position. A further object of the invention is to construct the table so that one or any number of the leaves can be pulled out, depending on the amount which the table is to be extended. A still further object of the invention is to arrange the parts in a simple and durable manner and so that they operate easily; such that the working parts and the stored leaves are not exposed and such that the various elements can be easily manufactured.

With the above objects in view the invention consists essentially in the arrangement and construction of parts hereinafter more particularly described and later pointed out in the appended claims, reference being had to the accompanying drawings, in which Figure 1 represents a side view of my extension table in the closed position.

Fig. 2 represents a plan view of the same with part of the top torn away to expose under construction, and with the table closed.

Fig. 3 is a view similar to Fig. 2 but with the table partially extended and three leaves up, or in use.

Fig. 4 represents an inverted plan view of the underside of the table in the closed position. I

Fig. 5 is an enlarged detailed vertical sectional view through the table, the section being takenlin the plane denoted by the line XX Fig. 4, and looking inwardly.

Fig. 6' is an enlarged detailed sectional view through the table, the section being taken in the plane denoted by the line YY- Fig. 4, and looking inwardly.

through the table, the section being taken in the plane denoted by the line Z-Z Fig. 4, and looking inwardly.

Fig. 8 is a perspective view of a fragmentary portion of the table top.

. Fig. 9 represents an enlarged detailed sectional view through the leaves showing the catches and hooks.

Fig. 10 is an inverted plan view of the parts shown in Fig. 9.

In the drawings like characters of reference indicate corresponding parts in the several figures.

' The table top comprises the customary top sections 1 and 2 provided with the usual rim 3, which top is carried by the pedestal 4L and foot pieces 5.

In the present instance the table is of the type known as a round table, and in the closed position the sections 1 and 2 are designed to close in against a stationary divisional strip 6 passing diametrically across the table and mounted on and secured permanently to a pair of spaced supporting strips 7 and 8 permanently secured to the upper end of the pedestal, and located in a position at right angles to the divisional strip. At the opposite sides of the divisional strip I locate a pair of transversely extending side strips 9 and 10 which are of the same height and length as the divisional strip and are parallel thereto and are carried by the ends of the supporting strips 7 and 8 to which they are permanently secured as indicated at 11. End strips 12 and 13 connect the outer ends of the divisional strip with the side strips and these end strips are fitted with a rimmed section 14 and are constructed so that they follow out the general'contour of the table top when the sections are brought together.

The above construction provides spaces at each side of the divisional strip and beneath the closed table top, which I utilize as stor age pockets indicated at 15 and 16 for the sets of table leaves 17 and 18. In the pres ent instance I have shown each set as comprising three separate leaves which, when in the stored position, are stacked one on top of the other in the pockets and with the lowermost leafof each stack resting on the end pieces 12 and 13 and the supporting strips 7 and 8.

In a location at opposite sides of the pedestal and approximately midway between the pedestal and the end strips, I locate lengthwlse extending stationary liner strips 19 and 20 which present narrow spanner parts 21 and wide ends 22 and 23 (see Fig. I

with a vertically disposed flange 26 which is secured by a lug as indicated at 27 to the under-sides of the side strips. These guide plates are provided to receive sliding guides, of which there are four, indicated at 28, 29, 30 and 31, which move with the table top sections, there being two connected to the underside of each top section. ,The guides are all of the detailed construction shown best in Fig. 8, where it will be seen they comprise a head piece 32 permanently attached to the table top section and a narrow extension 33 which forms the guide and rides on the guide plates.

The extensions associated with the top section 1 pass to the inner side of the ex tensions associated with the top section 2, and in this connection it is pointed out that the spaces reserved between the flange 26 and the lengthwise extendingstrip is just sufiicient to receive the extensions and allow them to move freely, sliding over the plate and between the divisional strip and the transverse strips. Angular reinforcing blocks 34 are supplied to strengthen the guides.

From the above arrangement it will be obvious that when the table top sections 1 and 2 are pulled apart the guides slide past each other and as the topis extended the pockets containing the leaves are exposed.

In order to raise the sets of leaves into the plane of the table top, when required, and to allow them to return into the pockets when the table is closed in, I have provided the following mechanical arrangement, which is the same at each end of the table and operates to control, in each instance, the stacks of leaves. Owing to the fact that this mechanical device is duplicated at either end, I have not considered it necessary to describe both ends and it will be here understood that either one can be manipulated from the end of the table as occasion may demand.

To the pedestal and in a location between;

the strips 7 and 8, I secure permanently a lengthwise extending guide strip 35, the opposite ends of which carry shdably, 1n each in the closed position of the table the hand grip 39 is just Within the rim of the table.

To theextremities of the cross head I secure a pair of flexible connections, such as cords 43 and 44 which are passed through notches 45 provided in the transversely extending side strips and then downwardlybeneath the lower leaf of the stack, and have their inner ends finally anchored as: indicated at 6 to'the side of the divisional strip. Where the flexible connections pass beneath the stack of leaves, the lowermost leaf is fitted with a block 47 around which the connection passes, and a strap48 is attached to the block and crosses the cord to hold it in position. of the table top the cords take the position as best shown in Fig. 5 of the drawings, where it will be observed that the leaves are allin the pockets and there is no slack in the cords.

From the above arrangement it will be apparent that after one has pulled out the table he can, by graspingv the hand grip 39 and pulling the lever endwise, cause the cross heads to move outwardly and, owing to the arrangement, eflect the raising=of the stack of leaves and, depending on the amount which they are raised, he can bring the top leaf into the plane of the table top; In order to remove the'top. leaf and the following ones as they are'brought upto position, I have provided hooks and catches 011 theleaves and catches on the inner sides of the table top section's, these beinglbest shown in Figs. 9 and 10 of the drawings. These are now described in detail.

The inner side of each section of the table top is notched as indicated at 4:9 and this notch receives a U-shaped catch 50 permanently secured to the underside of the section. Each leaf is provided at the one side with a spring hook 51 and at the other side with a catch 52 identical to that=50 and opefrating within a notch 53 provided iirthe lea When the leaves are-placed in the pockets it is necessary, owing to the fact thatthe catches are on the table top, that the hooks be all located tothe outer side of'the peck ets and the eyes to the inner side. With these hooks and catches provided, it is possible, by manipulating the table and lever, to extend the table with all the leaves up in the plane of the top. This action is In the closed position described in respect to two leaves, and it is to be understood that the action as described can be continued until all the leaves arellp in place. I v v I The first leaf is brought up into position by primarily opening up the table top in' the usual way to expose the leaf pocket. The hand grip 39 is then caught by the hand and after the lever has been released from the notch thelever is pulled outwardly bodily one notch displacement, which action through the cross heads effects the pulling of the cords sufficient to raise the uppermost leaf of the stack into the plane of the table top. The table top section is then, closed in to cause the catch of the table top to' engage the hook of the leaf and then, by reversing the action and pulling the table top out the leaf goes out with the top and again exposes the pocket. The hand lever .is then again manipulated, as above described, being pulled out a further notch displacement, and

locked, which action brings up the nextleaf to the plane of the table top. The table top is then again manipulated to cause the catch of the first leaf to engage the hook of the second leaf and with this accomplished the table is again extended to expose the pocket. This action can be continued until all the leaves are in position and the table is fully extended.

When one wishes to close the table, he releases the lever from the catch pin and allows it to pass inwardly, and in doing so gives enough slack in the cords to allow the innermost leaf to fall down below the level of the underside of the table top. The table is then closed in farther and the leaves are successively brought to a position over the pocket and each time a leaf is brought to this position the lever is manipulated to allow further slack in the cords.

In the above operation it is to be noticed that owing to the arrangement of the catches and hooks that the catches are free to escape from the hooks when the leaves pass down and that as the leaves are brought in they are all lined up over the pocket by engagement with the divisional strip.

The leaves of the table are usually fitted with lining teats 54 and in order to accommodate these I have provided vertical channels 55 on the inner sides of the side strips, to receive the teats in the stacked position of the leaves.

In the extension of the table it will be apparent that as the leaves pull out from the pocket they are carried by the wide ends 22 and 23 of the lengthwise extending strips 19 and 20.

What I claim as my invention is 1. In a multi-leaf extension table, centrally located pockets extending transversely of the table and located beneath the closed table top and receiving the leaves in stacks,

for withdrawing the uppermost leafcwith the table top andfrom above the pocket each time the leaf is brought into the plane of the table top.

2;-In a multi-leaf extension table, cenf-c trally located pockets passing. transversely of the table and located beneath the plane.

of the table top and receiving the leavesin stacks, flexibleielements for bodily raising a.

stack of leaves to bring a leaf into the plane of the table top and after the table has been extended to open the top, hand levers operatively connected with said flexible ele-,

ments, detent means for locking said levers in position, means for locking the first raised leaf to the top of the table to allow of the withdrawal of the leaf with the table top in the pulling out of the table and means for effecting the locking of the successively elevated leaves tothe previously elevated and withdrawn leaf in the manipulation of the table top.

3. In a multi-leaf extension table, centrally located pockets passing transversely of the table and located beneath the plane of the table top and adapted to receive the leaves in stacks, a pair of slidably mounted cross heads extending transversely of the table, means for pulling the cross heads outwardly and locking them in selected positions, flexible connections extending between the cross heads and the inner sides of the pockets, such connections passing underneath the stacks of leaves, whereby, in the manipulation of the cross heads, the stacks of leaves can be raised to bring the leaves successively into the plane of the table top and means adapted to connect the top to the first raised leaf and the leaves successively to one another in the manipulation of the table top.

4. In a multiple leaf extension table, a divisional strip passing centrally across the table and extending between the end section of the table top, transversely extending pockets located on opposite sides of the divisional strip and: contained beneath the plane of the table top and receiving the leaves in stacks, a lengthwise extending guide strip permanently secured to the under structure of the table, cross heads slidably mounted on the extending ends of the guide strip, flexible connections between the ends of the cross heads and the sides of the divisional strip, said flexible connections being guided over the outer sides of the pockets and being passed underneath the stacks of leaves, means for withdrawing the cross heads out,-

Wardly on the center strip and for locking them in selected Withdrawn positions, and engageable hooks and catches associated With the inner edges of the table top sections and the leaves.

5. In a multiple leaf extension table, centrally located transversely extending pockets located beneath the plane of the table top and receiving the leaves in stacks and comprising, a central divisional strip, parallel side strips, closure end strips and support ing strips connecting the undersides of the central and side strips and having the divisional strip passing into the plane of the table and separating'the closed sections of the table top, a lengthwise extending stationary guide strip cross beneath the pockets, cross heads slidably mounted on the extending ends of the guide strip, an operating lever pivotally secured to each cross head and having the outer end formed into a strips, underthe stacks of leaves and having their. inner ends secured permanently to the sides of the divisional strip, catches secured to the, inner sides of the table top sections and hooksand catches carried by the several leaves of the table, such hooks and catches beingpositioned so that the hooks of one leaf can be engaged Withthe catch of another andthe catches of the table sections With the hooks of the leaves."
